Trained AI outperforms biologists at spotting salmon lice
Researchers have taken over 120,000 images of salmon lice larvae in seawater and used them to train AI models. The models were much faster and more accurate than experienced biologists at identifying the parasites that feed on the skin and blood of salmonids.

Astronomers spot an extremely rare galaxy mega-merger
Scale in the universe is hard to understand from a purely human perspective. Many times, the math just doesn't sit well with our brains, which evolved to capture and process data about the world around us rather than grok the complexities of stellar dynamics and galaxy mergers. B
The language of play: Hyenas use facial expressions and vocalizations to de-escalate
Scientists observed spotted hyenas (Crocuta crocuta) playing in the wild and found that their precise, sophisticated communication is on par with that of many primate species. Hyenas play and romp with one another at all stages of life. Although juveniles play more frequently tha

The galaxy’s coldest “stars” may actually be alien megastructures
Scientists have identified new clues that could help astronomers spot one of the most famous hypothetical alien megastructures: a Dyson sphere. The study finds that red dwarfs and white dwarfs are the most promising stars to examine, since advanced civilizations could potentially

Tiny mountain lakes pose big, overlooked flood risks, new study warns
A new international study involving scientists from the University of Aberdeen has revealed a critical blind spot in global climate risk assessments—the growing danger posed by small alpine lakes formed by glacier retreat and permafrost thaw. Published in Nature Sustainability, t
